I like what Lewis has said, but want to add some more comments about the difference between timing and time for these meanings:

Timing

This gerund has 2 meanings:

(1) [uncountable] the skill of doing something at exactly the right timeperfect/good/bad etc timingHe was just walking into the restaurant when we got there. Perfect timing.

He told jokes with an exquisitesense of timing.

(2) [uncountable and countable] the time when someone does something or when something happens, especially when you are considering how suitable this istiming ofThe President and I did not discuss the timing of my departure.

Ferry schedules and precise timings are subject to weather conditions on the day of departure.

Time

The noun time has many other meanings, but one of them is "[countable and uncountable] the particular minute, hour, day etc when something happens or should happen"

a good time/a bad time

This might be a good time to start planning the new garden.

So, the main difference between timing and time is that if you want to:

(1) focus on a person's skill, use timing;

She always has good timing.

(2) speculate or talk abouthow appropriate a prospective schedule/plan is or might be, you can use timing or time (sometimes with subtle shifts in wording, as shown below);

The timing of next week's meeting is not great. / The time of next week's meeting is not great.

Your timing is not great; I have to rush off to a meeting. / This is not a good time; I have to rush off to a meeting.

Next week is not a good time for the meeting. / Next week is not good timing for the meeting.

Maybe this is a good time to talk about the budget. / Talking about the budget now is not good timing.
